Don't be a Menace to the South Central While Drinking Your Juice in the Hood - How Old Is Tre's Dad?

Around the beginning of the movie where Tre's mom drops him off at his dad's house, Tre says that his dad is a couple years older then him, but around the end of the movie when Tre is about to read his dad a bedtime story, his dad asks Tre why he didnt invite him to a party and Tre says because you have to be 18 and older, but Tre's going to the party and he said his dad is older than him.

This was a parody movie. You see references to Boyz N The Hood during the scene with Tre's father. He says that his father is younger than him in the beginning of the movie. It was a joke about the stereotype that Black people are always having children at a young age. It was also to show how immature and irresponsible his dad is.
